` All@ 23, 1938- G. WASTMAN DISPENSING DEVICE Filed Feb. 19, 1935INvENToR .G oth ad Wastman vBY TTORNEY Patented Aug. 23, 1938 UNITEDSTATES PATENT OFFICE 4 Claims.

This invention relates to improvements in a fountain shoe polish brushand appertains particularly to one that is easily filled, simplyoperated and clean to use thus saving' the cream or other material asnone is spilled or wasted, no unused surplus exposed to dry up and thehands of the user need not be soiled at all.

An object of the invention is to provide a fountain brush in which nounauthorized ejection (or more properly bleeding) of the material canoccur thus eliminating both the waste `and soiling incidental thereto. y

A further object of the invention is to provide a flow or deliverycontrolling mechanism for a fountain brush or the like wherein theoutlet valve in both operation and structure is independent of theejecting pressure providing mechanism though they are operable andusable simultaneously.

A further object of the invention is the provision of a fountain brushwith pressureapplying mechanism controlled by the users grip on thehandle thereof.

A further object of the invention is the provision in a fountainshoebrush or the like of the convenient combination of a material applyingdauber, brush and polishing cloth all instantly available and in acompact article.

A still further object of this invention is the provision of a fountainshoe polish brush of the nature and for the purposes set forth that ischaracterized by structural simplicity, durability and low cost ofproduction whereby the same is rendered commercially desirable.

To the accomplishment of these and related objects as shall becomeapparent as the description proceeds, the invention resides in theconstruction, combination and arrangement of parts as shall behereinafter more fully described, illustrated in the accompanyingdrawing and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly describedwhen reference is had to the drawing forming a part of this disclosurewherein like characters indicate like parts throughout the severalviews.

Figure 1 is a longitudinal vertical section of the device;

Figure 2 is a vertical transverse section thereof, as taken along theline 2-2 of Figure 1, in the direction indicated by the arrows;

Figure 3 is a fragmentary side elevation of the brush body showing themounting of the roll end of the polishing cloth; and

Figure 4 is a similar elevation of the opposite side of the brush bodyand the means for temporarily anchoring the free end of the cloth.

An elongated body 5 has an integral shaped handle E extendedlongitudinally from an end thereof. ries a brush 'I for the entirelength thereof and on the underside of the body 5, near the end remotefrom the handle is a small dauber brush 8.

Extending longitudinally through the body 5 and handle 6 is an axialbore 9 that is opened out as an enlarged cylindrical chamber I0 for thegreater part of the length of the body 5 and is lined with tubing I Ihaving an exterior flange I2 and interior threading I3 at its outer endto receive a screw cap 'I4 with an outer flanged edge I5 that with theflange I2 of the tube lining II seats in an annular pocket I6 in thebody 5 about the open end of the cylindrical chamber I0. A threaded boreI'I through this cap is normally closed by a knurled headed plug I8. Theremoving of this plug I8 Vor cap, I4 provides alternative sized threadedopenings to receive a filler tube of cream or the like.

Into the `cylinder tubing II a valve casing I 9 is threaded that extendsthrough an accommodating opening 20 in the body 5 and into the dauber 8.The upper rim 2| of the casing is flanged inwards to define a centralopening and provide a shoulder and the lower end 22 is cup shaped withan opening 23 in the base of the pocket to retain a ball valve 24normally seated by a compressed coil spring 25 whose upper end bearsagainst the under side of the flanged rim 2|. It is to be noted that theball seats low enough in the base or pocket of the casing that itsexposed portion hangs substantially below the casing so that the ballcan be temporarily unseated when the dauber is rubbed or pressed tightlyagainst an object such as a shoe.

The compressing or ejecting mechanism, as distinct from the bleed orvalve controlled port, comprises a plunger head formed of a leatherwasher 26 held by a metal disk 21 to the body 28 by a screw 29. Theplunger head body 28 has a threaded stem 30 that screws into the forwardend of the tubular stem 3| that is notched on its upper side for thegreater part of its length to provide teeth 32 having inclined forwardsides and substantially vertical rear walls. This stem extends back fromthe chamber ID through the bore y9, the latter being arched upwardlyonly in the handle 6 to give a dome shaped but narrow chamber 33. Anarcuate leaf spring 34 lies along the top of this chamber, its freeforward end engaging one of the teeth 32 of the plunger stem The upperside of the body proper carf while its rear end hinges on a transversepin 35 that retains a flanged finishing collar 36 in the handle end ofthe bore 9. Through an opening 31 in the top of the handle 6 a button38, carried by the leaf spring 34 projects to be engaged by the hand ofthe user as he grips the handle and to be reciprocated at will tooperate the plunger.

To rell the cylindrical chamber I0, dressing is inserted through the capi4 or plug I8 and the plunger withdrawn to the inner end of thecylinder, with the spring 34 pressed all the way down so that it liesinactive, by a double wire sling 39,

encircling a pin in the open end of the plungerI stem 3l, whose outerend is attached to a closure button 4I carried by the collar 36. Afterretracting the plunger, this sling and button can be returned toenclosed position Without further disturbing the plunger.

Along opposite sides of the body 5 are deep grooves 42 in one of which apairof spaced brackets 43 carry a polishing cloth 44 wound on a springroller 45. The free end of the cloth is doubled around a rod 46 Whoseextended ends are adapted to be held fast by a pair of spaced hooks 4Tin the groove on the opposite side of the body when the cloth is drawnaround the brush 1.

From the foregoing description taken in connection with the accompanyingdrawing, it will be manifest that a fountain shoe polish brush isprovided that will fulfill all the necessary requirements of such adevice but as many changes could be made in the above description andmany apparently widely different embodiments of the invention may beconstructed within the scope of the appended claims without departingfrom the spirit or scope thereof, it is intended that all matterscontained in the said accompanying specification and drawings shall beinterpreted as illustrative and not in a limitative or restrictivesense.

What is claimed as new is: l

1. In a pressure feeding device, a body, a chamber therein, a plungeroperable Within said chamber, a notched stem therefor, a bowed leafspring hinged at one end and engaging said notched stem at its free endand means for attening said leaf spring to extend its overall length toadvance said plunger stem notch by notch.

2.
